Answer 1

Answer:

Fracking involves the ______drilling to extract oil and natural gas from the rock. Select one: a. vertical b. lateral c. horizontal

The answer is option C (horizontal)

Explanation:

Fracking commonly known as Hydraulic fracturing is an oil and gas production technique that has enabled the extraction of oil and gas from rock (shale rock).

A fracturing fluid typically water with additives is pumped under high pressure into the drilling pipe to widen fractures in the rock or to create new ones and and allow trapped gas or crude oil to flow through a pipe to a wellhead at the surface, deep holes are drilled down into the shale rock. These fractures are held open by an injected proppant, typically sand and release hydrocarbons. Fracking takes about three to five days. Since shale reserves are typically distributed horizontally rather than vertically, horizontal directional drilling method is employed.

Some of the impacts of Fracking on the environment are:

• It consume large quantities of fresh water
• The injection of recovered fracking water into underground disposal wells and the high pressure used to extract oil and gas from rock may cause earthquakes.
• Fracking causes air and water pollution.
• Deforestation caused by fracking has deep effects on the environment.
